Question about 1998 Mercury Mountaineer
The car vibrates so bad that you can hardly turn right. We got a bearing for the right side and then the guy that fixes our car said that one was good and the left one was bad so he changed that. The car still shakes so bad we can hardly get around the corner. What else could it be?

If same tires as before & air pressure set correctly, or as usual, a humming when swerving, or turning one way or the other or both, it's usually a pretty good indicator.

The new tires could be out of balance,or even though they are new could have a bad belt in one of them,If it was doing this,the problem,if it was there before the tires were installed,have the front end checked.And you may need a front end alignment.If the tie rod,and ball joint were bad on that side,then chances are the other side may have bad front end parts also.You know it needs alignment after replacing tie rod ends don`t you?Eye balling the tie rod end does not get it back in line,and it may have needed the alignment anyway,Have a 4 wheel alignment done to make sure that is out og the equation while diagnosing the problem.

If this engine has a fan clutch check to see if the clutch spins freely when the engine is shut off. If its frozen that will cause a vibration which will shake the entire car.. The next item of interest would be the torque convertor in the transmision. They can shake a car very well also

this vehicle is known for suspension noises the most popular of which is the upper control arms but there is trailing arm bushings and ball joints that make almost the same identical sound. you can jack the car up on one side when the tire clears the floor hold the tire at 3 and 9 o' clock and rock left to right and feel for any play or lose feeling in the suspension it is supposed to be rigid the slightest play in any of these items you wont believe the racket they would make. do the same for the other side as well...then hold the tire at 12 and 6 o' clock and rock the tire up to down and do the same for the other side., if it is suspension bushings or upper ball joints you will find it like this. the lower ball joints however is a lil more tricky jack the car up on one side placing the jack under the lower control arm as close to the ball joint as you can go and jack till the tire is about 1-2 inches off the ground stick a bar under the tire and pry the tire higher off the ground and release repeat this till you can confirm weather there is play or not in the lower ball joint NOTE: it is best if you do this test with 2 people one to look at the ball joint while the other works the tire. for the trailing arm bushings you need 2 people for this one as well..... have someone drive the car forward 5 feet then step on the brake do it in reverse as well and step on the brake, fix your eyes to the back of the tire 3 o' clock on the driver side and the fender and see if there is excessive play.
NOTE: the wheel is supposed to give a little but that is about 1/2 of an inch front to back any more and these bushings are bad.

Rebleed the brakes, front to rear starting with the furtherest wheel in back. It may take several times to get all the air out of the system. You also need to center the safety valving, the brake lights on the dash will go out when its right. It can take 3 times. Your right caliper could be sticking and you may need to grease or recheck the hardware.
There are also bearings under the tops of the shock towers on some Mercury models. They give the same problems as bad upper balljoints. Check your part number for the 1/2 shaft if that is the side sticking out. Some manufactuers used 2 sizes of shafts to reduce Torque steer and I do not know if it is possible to install the wrong side, but recheck the number.
If you had a change in the balljoint you usually need a frontend alignment. With frontdrive vehicles it can be a 4 wheel alignment. You do not know how much the tierod or rack and pinion ends were previously adjusted to compensate for wear. And if the old side sticks out more than the new side you may have bad parts there too.
A Vacuum bleeder pump does a nice job in lieu of a helper for the brakes. I do these alot and sometimes you just wonder why some are easy and identical ones are hard.
